In-situ anion-exchange synthesis AgCl/AgVO3 hybrid nanoribbons with highly photocatalytic activity

A simple and easily operating strategy, in-situ anion-exchange method, has been developed for synthesis of AgCl/AgVO3 heterojunctions. Cube-shaped AgCl nanoparticles of approximately 50-100 nm were closely attached to the surface of AgVO3 nanoribbons. The content of AgCl in heterojunctions could be controlled by adjusting the NaCl concentration in the ion-exchange reaction solution. The photocatalytic efficiency of AgCl/AgVO3 heterojunctions was far higher than that of pure AgVO3 nanoribbons through degradation of methyl orange solution. This approach is a general method and can be extended to the synthesis of a variety of other AgVO3 heterojunctions.
